                TIME per switch                COST per swith             QUANTITY                                   

type A          4 minutes               3 dollars                          A

type B          6 minutes               6 dollars                          B

TOTALS         37 hours               2040 dollars

37%2Ahours%2A60%2A%28minutes%2Fhour%29=2220%2Aminutes

system%284A%2B6B=2220%2C3A%2B6B=2040%29

These should give system%28highlight%28A=180%29%2Cand%2Chighlight%28B=250%29%29
